Don't Ask Wyvern

One allowance here buys 656,800 EXP, the best of the 3 Lv 56 Carpenter tradecraft leves that record EXP: the runner-up manages 338,440 EXP, 48% less.

Across that rung the return runs from 320,970 EXP to 656,800 EXP per allowance — 3 distinct figures spanning 105%, so the wrong pick leaves 335,830 EXP of the allowance unspent.

On whether to wait: the best Lv 58 Carpenter tradecraft leve returns 484,390 EXP per allowance, 26% less than the best on this rung, while the Lv 54 rung behind tops out at 473,220 EXP.

At Lv 56 this data holds 54 leves paying EXP across 3 categories: the 24 Tradecraft ones average 390,755 EXP per allowance, the 3 Fieldcraft ones 1,032,386 EXP and the 27 Grand Company ones 195,640 EXP, which puts this leve 68% above its own category's average.

Gil ranks it differently: 998 gil per allowance is 2nd of 3 on the same rung against 1st on EXP, with the best there paying 1,123 gil.

Hallowed Chestnut Composite Bow ×1 is a Lv 56 Carpenter recipe, 3 steps deep through 7 intermediates, costing 48 units of raw material and 62 crystals.

Handing that in returns 13,683 EXP and 21 gil for every unit of raw material the order swallows, and the tree needs Alchemist, Carpenter, Goldsmith and Weaver.
